Ecology and ecotoxicology have different historical roots, despite their similar names, but are slowly converging to meet the challenge of addressing massive global proliferation release chemicals in environment. The conceptual, methodological, review standard research papers this special issue reflect emerging trend blending ecological ecotoxicological perspectives assess impacts freshwater ecosystems. Assessing community ecosystem chemical contaminants is complex, however, will require...
Summary A major challenge in environmental risk assessment of pollutants is establishing a causal relationship between field exposure and community effects that integrates both structural functional complexity within ecosystems. Pollution‐induced tolerance (PICT) concept evaluates whether have exerted selection pressure on natural communities. PICT detects pollutant has eliminated sensitive species from thereby increased its tolerance. the potential to link assessments ecological chemical...
Silver nanoparticles (AgNP) are increasingly used as antimicrobials in consumer products. Subsequently released into aquatic environments, they likely to come contact with microbial communities like periphyton, which plays a key role primary producer stream ecosystems. At present, however, very little is known about the effects of on processes mediated by periphyton communities. We assessed citrate-coated silver and ions (dosed AgNO3) five functional end points reflecting community...
With the accelerated use of silver nanoparticles (AgNP) in commercial products, streams will increasingly serve as recipients of, and repositories for, AgNP. This raises concerns about potential toxicity these nanomaterials environment. Here we aimed to assess impacts chronic AgNP exposure on metabolic activities community structure fungal bacterial plant litter decomposers central players stream ecosystems. Minimal variation size surface charge indicated that were rather stable during...
Nanotechnology risk management strategies and environmental regulations continue to rely on hazard exposure assessment protocols developed for bulk materials, including larger size particles, while commercial application of nanomaterials (NMs) increases. In order support corroborate NMs workers, consumers, the environment it is crucial establish impact biopersistence at realistic doses. future, such data will allow a more refined categorization NMs. Despite many experiments NM...
Wastewater treatment plants (WWTPs) play an important role in retaining organic matter and nutrients but to a lesser extent micropollutants.Therefore, treated wastewater is recognized as major source of multiple stressors, including complex mixtures micropollutants.These can potentially affect microbial communities the receiving water bodies ecological functions they provide.In this study, we evaluated flow-through channels consequences exposure mixture stream different percentages urban...
Effluents of wastewater treatment plants can impact microbial communities in the receiving streams. However, little is known about role microorganisms as opposed to other constituents, such nutrients and micropollutants. We aimed therefore at determining on diversity function periphyton, key used a flow-through channel system grow periphyton upon exposure mixture stream water unfiltered or ultra-filtered wastewater. Impacts were assessed biomass, activities tolerance micropollutants, well...
Characterization of carbon nanotube dispersions requires measurement both, concentration and surface area.
Fundamental knowledge gaps on the bioaccumulation, trophic transfer and effects of nanoplastics in fresh waters limit estimation their ecological risks.
The rapid proliferation of silver nanoparticles (AgNP) in industry and the environment requires realistic toxicity assessments based on approaches that consider biological complexity ecosystems. Here we assessed acute carbonate-coated AgNP and, for comparison, AgNO3 (Ag(+)) by using a model system consisting decomposing plant litter associated fungal bacterial decomposers as central players functioning stream Little variation size surface charge during experiment indicated used were...
Plastics, especially microplastics (<5 mm in length), are anthropogenic polymer particles that have been detected almost all environments. Microplastics extremely persistent pollutants and act as long-lasting reactive surfaces for additives, organic matter, toxic substances. Biofilms microbial assemblages a sink particulate including microplastics. They ubiquitous freshwater ecosystems provide key services promote biodiversity help sustain ecosystem function. Here, we conceptual framework to...
Environmental risk assessment associated with aquatic and terrestrial contamination is mostly based on predicted or measured environmental concentrations of a limited list chemicals in restricted number compartments. High resolution mass spectrometry (HRMS) can provide more comprehensive picture exposure to harmful chemicals, particularly through the retrospective analysis digitally stored HRMS data. Using this methodology, our study characterized various compartments including 154 surface...
Preventing and remedying fresh waters from chemical pollution is a fundamental societal scientific challenge. With other nonchemical stressors potentially co-occurring, assessing the ecological consequences of reducing loads in environment arduous. In this case study, we comparatively assessed community structure, functions, tolerance stream biofilms to micropollutant mixtures extracted deployed passive samplers at wastewater treatment plant effluents. These were growing up- downstream one...
Microbial life in natural biofilms is dominated by prokaryotes and microscopic eukaryotes living dense association. In stream ecosystems, microbial influence primary production, elemental cycles, food web interactions as well water quality. Understanding how biofilm communities respond to anthropogenic impacts, such wastewater treatment plant (WWTP) effluent, important given the key role of ecosystem function. Here, we implemented 16S 18S rRNA gene sequencing upstream (US) downstream (DS)...
